Stop the Keystone XL Oil Pipeline.

Lt. Dan Choi will submit our letter of solidarity to the court on September 1st.

Since last Saturday, DADT activist Lt. Dan Choi, Firedoglake's Jane Hamsher and hundreds of others have been arrested at the White House for protesting the Keystone XL pipeline that would feed oil from the Canada Tar Sands to big oil refineries in Texas.

This 1,500 mile pipeline would represent the biggest carbon source in the world outside of Saudi Arabia and, as climate activist and protest organizer Bill McKibben says, "would essentially be 'game over' for the climate" - but there's still time to stop it from being built. President Obama has the power to stop the pipeline before construction begins in the next few weeks - which is why these brave activists are out there, putting their bodies on the line, day after day.

Those of us who can't be in Washington DC for the Tar Sands action must work to ensure this war is waged not only in the nation's capital, but across the country as well.

Lt. Dan Choi faces trial on September 1st for his participation in the Tar Sands protests and will enter the names of Firedoglake activists who oppose the Keystone XL project to the court as evidence. Can you add your name to our important letter to be entered into the court in defense of the Tar Sands protesters on September 1st?

We, the undersigned, stand in solidarity with all Tar Sands activists in opposition to the proposed Keystone XL pipeline.

The Keystone XL pipeline, which would stretch 1,500 miles and open up a vast expanse of tar sands oil for drilling and refining, would spell doom for any effort to control greenhouse gas emissions. It will destroy communities not only between Canada and Texas, but the world-over.

We urge President Obama to stop all plans to build the Keystone XL pipeline.

Lt. Dan Choi will deliver your signature to the court record when he faces trial for protesting in front of the White House on September 1st.
